Begin by preheating your oven to 375°F (190°C). This ensures the quiche bakes evenly.
In a medium skillet, heat the olive oil over medium heat. Once hot, add the blanched broccoli florets and sauté for 3-4 minutes until they are tender yet still vibrant. Remove from heat and allow to cool slightly.
In a large mixing bowl, crack the eggs and beat them lightly. Add the whole milk, garlic powder, onion powder, ground nutmeg, and a pinch of salt and black pepper. Whisk the mixture thoroughly until all ingredients are well combined.
Fold in the shredded sharp cheddar cheese and grated Parmesan cheese, mixing gently to ensure even distribution throughout the egg mixture.
Carefully incorporate the sautéed broccoli into the egg and cheese mixture, folding it in gently to avoid breaking the florets.
Pour the assembled mixture into the pre-made pie crust, ensuring it is spread evenly throughout.
Place the quiche in the preheated oven and bake for 35-40 minutes, or until the egg is set in the center and the top is beautifully golden brown. A slight jiggle is perfectly fine!
Once baked, remove the quiche from the oven and allow it to cool for about 10 minutes. This resting time makes slicing easier and helps the flavors settle.
Notes
Serve warm, garnished with freshly chopped parsley for a pop of color.
